“…Similar extensive works or experimental studies of film condensation were performed extensively (Dhir & Lienhard, 1971;Popiel & Boguslawski, 1975;Sukhatme et al, 1990;Cheng & Tao, 1994). The use of porous structure for extensive surface of condensation was not a new idea and numerous related studies were found in open literature (Jain & Bankoff, 1964;Cheng & Chui, 1984;Masoud et al, 2000;Wang & Chen et al, 2003;Wang & Yang et al, 2003;Chang, 2008). Metallic foams possess a three-dimensional basic cell geometry of tetrakaidecahedron with specific surface area as high as 10 3 -10 4 m 2 ·m -3 .…”
